EPTThe Big Programming Thread - Page 546

Thread Rules 1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution. 2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20) 3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible. 4. Use [code] tags to format code blocks. | ||

+ Show Spoiler + print "Gimme the string boy:" user_input = gets.chomp.downcase! if user_input.include? "s" user_input.gsub!(/s/, "th") else puts "no 's' in your string" end puts "adios, #{user_input}!" was that if i put in a lower case string it would give an error that said include? not defined which didn't make any sense to me but it would work if the string was uppercase to begin with. Am i gonna learn why this occurs later or am i missing something basic? | ||

I don't think thats quite it, the downcase method works and prints out a downcase version of my string and then goes through the program correctly. Its when my string is already downcased that I get an error and nothing happens. | ||

Obviously, you'll need an end there too  | ||

(false == somevar) can make sense in some situations where you're similar sanity checks at the start of functions and the operand is predictable. Instead of having to read if(somevar ==before I get to the actual information I care about on that line I can simply read if(conditionand know what the rest of the line will be. Just playing devil's advocate, though I have run into this pattern from time to time when contributing to open source javascript libraries. | ||

If you have shit static checking that won't catch assignment errors, first see if that can be improved, because it will catch other things which yoda code doesn't help. | ||

You're also assigning results of destructive (bang!) operations to variables when you appear to be expecting the results of the non-destructive versions. Here's a simplified version that utilizes destructive methods: user_input = gets.chomp.downcase | ||

If you're doing distributed fault tolerant computing with like a Spark cluster or something then Spot instances can be the way to go. | ||
